The statement " <span>y </span><span>varies directly as </span><span>x </span><span>," means that then </span><span>x </span>increases,<span>y </span><span>increases </span><span>by the same factor so we have: y/x=k
for question 1 then: 15/5=3
so the direct variation equation is y=3x
Now if x=9 you only have to replace x in your equation and you get:
y=3*9=27</span>

So here is how we find the answer to this given problem.
<span>The formula for area is: A=(l)(w)
So, A=(2x)(8-x²)
A=16x-2x³
dA/dx = 16-6x²
then you will use calculus to get the absolute local maximum of x
by letting dA/dx = 0
then wha you will get is x = 2sqrt(6)/3
so the area would be= 64 * sqrt(6) / 9
</span>or 64√<span><span>6/</span>9.
Based on the choices given, the answer would be option D.
Hope this answer helps.</span>
